Variables not being printed out correctly on Alerta integration

[skylenet]

I have the following .tick script :

stream
  .from()
    .measurement('cpu')
    .where(lambda: "cpu" == 'cpu-total')
  .groupBy('host', 'cpu')
  .window()
    .period(10s)
    .every(10s)
  .mapReduce(influxql.mean('usage_idle'))
  .eval(lambda: 100.0 - "mean")
    .as('used')
  .alert()
    .id('kapacitor/{{ .Name }}/{{ .Group }}')
    .message('<b>{{ .Name }}</b>: Group: <b>{{ .Group }}</b> Usage: <b>{{ index .Fields "used" | printf "%0.0f" }}%</b>')
    .stateChangesOnly()
    .warn(lambda: "used" > 80.0)
    .crit(lambda: "used" > 90.0)
    .alerta()
      .resource('{{ .ID }}')
      .event('{{ .Name }}')
      .value('{{ index .Fields "used" | printf "%0.0f" }}')
    .log('/tmp/alerts_cpu.log')
    .hipChat() 

The alert does go to Alerta but the resource,event and value fields are not printing out the correct values. They simple print out "{{ .ID }}" as a string.

Example response from Alerta:

    },

}

Any idea if this is a bug or am I doing something wrong?

thanks in advance :)

I noticed about this PR: #228

So I downloaded a recent nightly build ( Kapacitor 0.11.0~n1457683528 (git: master 1671023) and it seems to be working there 👍

Hi,

even with the latest nightly I still have the problem, that I can not use a tag in environment section:

        .alerta()
          .value('{{ index .Fields "mean" | printf "%.2f" }} %')
          .resource('{{ index .Tags "service" }}')
          .environment('{{ index .Tags "env" }}')

The env tag is correctly printed in the message however and the service tag is correctly printed as the resource. Thats a strange behavior here :/
